Enhancing the spectral selectivity and thermal stability of the absorber used in the
concentrated solar power system would boom the conversion efficiency of solar energy to …

Achieving broadband absorption has been a topic of intensive research over the last
decade. However, the costly and time consuming stage of lithography has always been a …

We present graphene metasurface based efficient and broadband solar absorber composed
of a periodically arranged array of C-shaped metasurface placed above the dielectric layer …

This paper presents a novel approach for designing dual-band absorbers based on
graphene and metallic metasurfaces for terahertz and mid-infrared regimes, respectively …

We numerically investigate the optical performance of a periodically patterned H-shaped
graphene array by the finite-difference time-domain (FDTD) in the mid-infrared region. The …

This paper presents the design and analysis of broadband metamaterial absorbers with
single and dual absorption bands from terahertz to infrared frequencies. The absorbers are …

An ultra-wideband metamaterial absorber is developed, which is polarized-insensitive and
angular-stable. Three layers of square resistive films comprise the proposed metamaterial …

Inspired by the growing family of Van der Waals materials, hBN supported phonon
polaritons have attracted much attention due to their inherent hyperbolic dispersion …

Broadband optical absorbers are increasingly in demand in various applications, including
solar cells and radiative cooling systems. Among various types of structures, absorbers …

This article presents the design of two dual-band graphene-based absorbers for terahertz
frequencies. The absorbers are composed of two-dimensional (2D) arrays of ribbons and …
